Can hear a tappety noise thats comming from the top of the block. This is on a NON turbo mk4 gti 1.8 20v.
There is no back pressure and the oil doesnt seem to 'flick' out of the oil cap when running.
Is this normal?
It sounds like its running dry and the oil level is perfect. no coolant / oil mix
Could this be the oil pump. this a common thing?
